Business Application Migration Aws Cloud

The client faced several infrastructure challenges:

• Multiple websites running on a 2-tier architecture (UI + Database) across different web servers
• SQL Server Standard edition databases requiring seamless integration
• Need for high availability and disaster recovery across multiple regions
• Ensuring security, monitoring, and efficient storage management
• Transitioning a legacy on-premises environment to AWS Managed Services without disrupting operations

The client required a secure, reliable, and fully managed cloud solution for their growing global user base.

App Maisters designed and executed a comprehensive migration strategy on the AWS platform:

Key Components of the Solution:

• Web Server Provisioning & Deployment: Web servers provisioned under an Application Load Balancer (ALB) with all websites deployed seamlessly.
• Network Segmentation & Security: Servers placed in private subnets, except for ALB and RDP servers in public subnets for optimal security and accessibility.
• File Server Integration: Mounted file servers for efficient deployment and user upload management.
• SQL Server Integration: SQL Server Standard License integrated into AWS infrastructure for database operations.
• High Availability Active Directory & DNS: Deployed across two Availability Zones (AZs) with EC2 and file server instances.
• Data Backup & Storage: AWS S3 used for resilient backup of data and logs.
• NAT Gateway Integration: Ensured high availability and network connectivity using AWS managed services.
• Automated Snapshots: Periodic snapshots configured for disaster recovery and operational reliability.
• EBS Management: Automated hard disk expansion to manage data growth cost-effectively.
• Monitoring & Tracking: AWS CloudWatch for real-time monitoring and AWS CloudTrail for detailed API and account activity tracking.

Before:

On-premises 2-tier web + DB servers → Manual backups → Limited scalability → Complex management

After:

AWS-managed infrastructure → Automated backups and snapshots → High availability → Scalable, monitored, and secure architecture

After the AWS migration, the client achieved:

• Seamless migration of .NET-based applications to AWS Cloud
• Robust, scalable, and highly available cloud infrastructure
• Improved operational reliability and security
• Centralized monitoring and automated management
• Cost-effective storage and resource utilization
• Disaster recovery readiness and data protection

The solution enabled the client to operate a secure, scalable, and reliable cloud platform supporting global B2B operations.

• IT Operations: Manage web servers, database, and cloud infrastructure efficiently
• Administrators: Monitor system performance, backups, and network security
• Management: Ensure high availability, scalability, and disaster recovery across global platforms

App Maisters successfully migrated the client’s .NET-based applications to AWS Cloud, creating a highly available, scalable, and secure cloud infrastructure. The solution improved operational reliability, enabled seamless global access, and provided robust monitoring, backups, and cost-effective management for future growth.
